This makes me wonder, are the bits = the power turned on for exactly 1/320th sec, every 1/160th sec? Or is the power on/power off ratio something different? Does it vary by protocol? What are the pros and cons?
- danbruc 2y agoWithout looking up what kind of encoding and modulation they are using, I would assume that they are sending a continuous sine wave at the carrier frequency that has the bits - probably after encoding the raw data bits with some error correction code - modulated onto it by changing frequency, amplitude, phase, or a combination of them depending on the value of each bit or group of bits.
